Implement mmap via struct drm_gem_object_functions.mmap in amdgpu, radeon and nouveau. This allows for using common DRM helpers for the mmap-related callbacks in struct file_operations and struct drm_driver. The drivers have their own vm_ops, which are now set automatically by the DRM core functions. The code in each driver's verify_access becomes part of the driver's new mmap implementation. With the GEM drivers converted, vmwgfx is the only user of ttm_bo_mmap() and related infrastructure. So move everything into vmwgfx and delete the rsp code from TTM. This touches several drivers. Preferably everything would be merged at once via drm-misc-next. v4: * rebase on top of amdgpu hot-unplug changes v3: * tidy up the new mmap functions in amdgpu and radeon (Christian) v2: * removal of amdgpu fbdev mmap already merged (Christian) * rebase on top of amdgpu fixes [1] (Felix) * replace pr_err() with drm_err() in vmwgfx patch (Zack) * several typos [1] https://patchwork.freedesktop.org/series/88822/ Thomas Zimmermann (7): drm/ttm: Don't override vm_ops callbacks, if set drm/amdgpu: Implement mmap as GEM object function drm/radeon: Implement mmap as GEM object function drm/nouveau: Implement mmap as GEM object function drm/vmwgfx: Inline ttm_bo_mmap() into vmwgfx driver drm/vmwgfx: Inline vmw_verify_access() drm/ttm: Remove ttm_bo_mmap() and friends drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.c | 46 ------------- drivers/gpu/drm/amd/amdgpu/amdgpu_dma_buf.h | 2 - drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 4 +- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c | 55 +++++++++++++++ drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 75 --------------------- drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.h | 1 - drivers/gpu/drm/nouveau/nouveau_bo.c | 10 --- drivers/gpu/drm/nouveau/nouveau_drm.c | 3 +- drivers/gpu/drm/nouveau/nouveau_gem.c | 36 ++++++++++ drivers/gpu/drm/nouveau/nouveau_ttm.c | 49 -------------- drivers/gpu/drm/nouveau/nouveau_ttm.h | 1 - drivers/gpu/drm/radeon/radeon_drv.c | 3 +- drivers/gpu/drm/radeon/radeon_gem.c | 49 ++++++++++++++ drivers/gpu/drm/radeon/radeon_ttm.c | 65 ------------------ drivers/gpu/drm/radeon/radeon_ttm.h | 1 - drivers/gpu/drm/ttm/ttm_bo_vm.c | 60 ++--------------- drivers/gpu/drm/vmwgfx/vmwgfx_ttm_buffer.c | 9 --- drivers/gpu/drm/vmwgfx/vmwgfx_ttm_glue.c | 53 ++++++++++++++- include/drm/ttm/ttm_bo_api.h | 13 ---- include/drm/ttm/ttm_device.h | 15 ----- 20 files changed, 202 insertions(+), 348 deletions(-) base-commit: 28dddc0c90bc6464be4c5e3224a293c022564a4e prerequisite-patch-id: c2b2f08f0eccc9f5df0c0da49fa1d36267deb11d prerequisite-patch-id: c67e5d886a47b7d0266d81100837557fda34cb24 -- 2.31.1
